Abstract
Abstract A display apparatus for a bicycle having a speed changer includes a display (10) switchable between a running mode for displaying running information such as time, running speed or running distance, and a shifting mode for displaying shifting information such as a speed stage of the speed changer; a switch and sensors (7a, 7b, 17) for generating a command to switch the display from the running mode to the shifting mode; and an automatic mode change device (12a, 12f) for automatically switching the display from the shifting mode to the running mode. The automatic mode change device includes a control unit (12a) and a timer (12f). The control unit transmits the shifting information in place of the running information to the display device in response to a signal from the sensor or switch. The timer starts measuring time in response to the signal from the sensor or switch. Upon lapse of a predetermined time (t), the control unit transmits the running information in place of the shifting information to the display.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
142 words
A display apparatus for a bicycle having a speed changer, comprising: a takeup element for winding a control cable; a shifting device for rotating said takeup element, wherein said shifting device comprises shift levers adapted to be manipulated by a user; display means switchable between a running mode for displaying running information and a shifting mode for displaying shifting information; switching command generating means for generating a command to switch said display means from said running mode to said shifting mode, said switching command generating means including contact sensors provided to said shift levers so that manipulation of said shift levers causes said generation of said command; and automatic mode change means for automatically switching said display means from said shifting mode to said running mode upon lapse of a predetermined time after switching of said display means to said shifting mode.
