A leaning vehicle 1 includes a headlamp 81. The headlamp 81 includes: an upper light source 100A including LEDs 101, 102, and 103 disposed laterally adjacent to each other; a lower light source 100B including LEDs 104 and 105; an upper reflector 90A including reflector elements 91, 92, and 93; and a lower reflector 90B including reflector elements 94 and 95. In a front view of the vehicle, a length L1 between the right and left ends of the lower light source 100B is shorter than a length L2 between the right and left ends of the upper light source 100A, and a horizontal distance L3 between the left ends of the upper and lower light sources 100A and 100B is equal to a horizontal distance L4 between the right ends of the upper and lower light sources 100A and 100B.


It is an object to provide a content reproduction apparatus which, without requiring cumbersome operations, can reproduce content that a specific user instructs to be reproduced, in a place corresponding to movement of the specific user. A controller (102) of a receiver (5) determines that the user stays in a room where a speaker which is closest to a user terminal, transmits a digital audio signal to the speaker, and does not transmit the digital audio signal to other speakers. In the case where the user stays in a room (1 B) as shown in Fig. 3A, for example, a speaker (7B) is closest to the user terminal (9). Therefore, content such as a music is output from the speaker (7B), and not output from a speaker (7A) and a speaker (7C). In the case where the user moves to a room (1A) as shown in Fig. 3B, the speaker (7A) is closest to the user terminal (9). Therefore, the controller (102) of the receiver (5) transmits the digital audio signal to the speaker (7A) which is closest to the user terminal, and does not output the digital audio signal to the other speakers.

A head device, including: a mounting head which has a tip mounting portion to which a tip is to be fitted, the tip including a suction port to suck an object and discharge the sucked object, and a shaft member configured to move in an up-down direction to generate a suction force and a discharge force at the suction port; a first motor configured to generate a drive force for moving the shaft member in the up-down direction; a frame member which holds the mounting head and the first motor; a second motor configured to generate a drive force for moving the frame member in the up-down direction; and a control unit which controls movement of the shaft member in the up-down direction by controlling drive of the first motor and height position of the head by controlling drive of the second motor.


The task is to reduce the burden on a user who uses a terminal device to reproduce a content. An information transmission device (24) includes a voice recognition section (52) for recognizing a phrase (W) of guide voice represented by a voice signal (G), an information specifying section (54) for specifying identification information item (D) corresponding to the phrase (W) recognized by the voice recognition section (52) from a plurality of identification information items (D) corresponding to mutually different phrases, and transmitting means (56, 46) for transmitting the identification information item (D) specified by the information specifying section (54) to a terminal device capable of reproducing the content represented by the identification information item (D).

A storage portion is disposed behind a link mechanism and ahead of a seat in a front-rear direction of a body frame. The storage portion defines a space storing an article in such a way as to be taken out of the space. As viewed from a direction along respective turning axis of an upper cross member and a lower cross member of the link mechanism, the storage portion overlaps both of the upper cross member and the lower cross member at least temporarily when the body frame is caused to lean leftward or rightward with a maximum extent from an upright condition thereof.

A drum foot pedal apparatus includes: a coil spring (60) imparting resilient self-retuming force to a foot board (50); a rod member or an adjusting bolt (65) supported by a support section (23) provided on a support post member (21, 22); and a tension adjustment mechanism (100) provided between the coil spring and the rod member or the adjusting bolt. The tension adjustment mechanism includes a connection position adjustment section (70, 90) that interconnects the lower end of the coil spring and the rod member or the adjusting bolt above the support post member, and that is constructed to permit adjustment of a connection position between the lower end of the coil spring and the rod member or the adjusting bolt at a position above the support section. Thus, it is possible to effectively prevent frictional wear of component parts and generation of noise and achieve an enhanced operability in the tension adjustment, with a simple construction having a minimized number of component parts.


A data positioning method includes obtaining positional information indicating a position which is designated by operation of an operation unit in any region among a plurality of regions, each of the plurality of regions corresponding to a predetermined direction along which values of a series of pieces of data are varied and being provided for designating a position of the series of pieces of data in the predetermined direction, and the plurality of regions include at least one region for designating a plurality of discrete positions of the series of pieces of data in the predetermined direction. The method further includes determining the position for designating a portion of data corresponding to the obtained positional information, any one position being determined among the plurality of discrete positions when positional information indicating a position in the region for designating the discrete positions is obtained.


A signal processing device includes: a calculating unit performing calculation using signal levels of first and second acoustic signals; a determining unit, based on a result of a comparison between: the signal level of at least one of the first and second acoustic signals before the calculation; and a result of the calculation, determining whether a component of a third acoustic signal to be output from a position between a position from which the first acoustic signal is output and a position from which the second acoustic signal is output is included in the first and second acoustic signals; and a signal generating unit generating the third acoustic signal from the first and second acoustic signals when the determining unit determines that the component of the third acoustic signal is included in the first and second acoustic signals.
