The housing 7 has a liquid crystal display element 12 facing the display window 8, and a clock function, and also displays the running speed and distance by inputting the rotational pulse output from the speed center 4. A one-chip microcomputer-type calculation integrated circuit that calculates the following and selectively displays any of traveling speed, traveling distance, and time on the display element 12 by pressing the speed key switch 9a, the distance key switch 9b, and the time key switch 9c. 13 and a speedometer drive battery (not shown) for driving these are housed.Furthermore, on the back of the rear case 11, the integrated circuit 13 receives rotation pulses from the speed center 4. An input terminal 15 made of a conductive wire material for inputting an output is exposed in the vertical direction. Further, 16, 16 are a pair of mounting grooves recessed on both left and right sides of this housing 7, and 17 is a working end 17.
A is a switching micro switch installed in the housing 7 so as to protrude from one mounting slot 16, and when the operating end 17a protrudes from the slot 16, the micro switch 17 is connected to the clock key switch 9c. The circuit of the board 14 is switched so that it functions as a clock in the same way as when the active end 17a is pressed and released, while the circuit of the board 14 is switched so that it functions as the speedometer when the active end 17a is pressed. This is to switch between.

Since the output terminal 25 of the speed sensor 4 is also in sliding contact with the input terminal 15 of the housing 7 when it is attached to the mounting frame 3 with the button a pressed, the speedometer functions as a speedometer, and on the other hand, When the speedometer is not in use, the speedometer housing 7 is taken out from the mounting frame 3 and carried. At this time, the working end 17a of the micro switch 17 is released from the pressure and protrudes into the mounting slot 16. In this state, the circuit of the board 14 switches to a clock function and digitally displays the time on the display window 8.
It serves as a clock.
