Transmitter for vehicle remote control system
First Claim
1. A remote control transmitter used for a switching of a state of a door lock device between a locked state and an unlocked state and so on comprising:
- a portable-size case;
at least one operating button provided on an outer surface of the case;
a rechargeable secondary battery provided within the case;
a solar battery provided on the outer surface of the case and rechargeably connected to the secondary battery; and
a generator for generating a coded signal,wherein when the operating button is pushed, electric current is fed from the secondary battery to the generator; and
wherein one of terminals of the operating button is connected to a positive terminal of the secondary battery and the other of the terminals of the operating button is connected to a positive terminal of the generator.

Abstract
A remote control transmitter used for a switching of a state of a door lock device between a locked state and an unlocked state and so on comprises a portable-size case, operating buttons provided on an outer surface of the case, a secondary battery provided within the case, a solar battery provided on the outer surface of the case and rechargeably connected to the secondary battery, and a generator for generating a coded signal. One terminal of each operating button is connected to a positive terminal of the secondary battery and the other terminal is connected to a positive terminal of the generator. When one of the operating buttons is pushed, electric current is fed from the secondary battery to the generator.

6. A remote control transmitter used for a switching of a state of a door lock device between a locked state and an unlocked state and so on comprising:
-
a portable-size case; at least one operating button provided on an outer surface of the case; a rechargeable secondary battery provided in the case; a solar battery provided on the outer surface of the case and rechargeably connected to the secondary battery; and a generator for generating a coded signal when the operating button is pushed; a feeding unit provided between the generator and the secondary battery, said feeding unit having a first input port for receiving electric current as an operating signal when the push button is pushed, a second input port for receiving a feedback signal as an operating signal and means for feeding power from the secondary battery to the generator, wherein the unit feeds the power from the secondary battery to the generator when the unit receives one of the operating signals; a detecting means of said generator for detecting the feedback signal; and a display portion adapted to operate in response to an output of the generator; and
whereina power output of the solar battery is substantially less than an instantaneous transmitting power of the generator. - View Dependent Claims (7, 8, 9, 10)
