Abstract

PROBLEM TO BE SOLVED: To enable normal reception of a remote control signal even when a light receiving means for the remote control in the VTR side can be used. SOLUTION: A microcomputer 1 confirms a remote control signal which is always input and performs, when the remote control signal has the normal format, the operation suitable for this format, for example, various operation controls of VTR 6 such as recording and reproducing operations. However, when the remote control signal does not have the normal format, the microcomputer 1 outputs a control signal 5 to cutoff a switch 4. The switch 4 is in the cutoff condition, collision of the remote control signals from the first and second light receiving means 2 and 3 for remote control can be avoided.

Here, when the VTR 6 is stored in a storage shelf or the like and used, if the front cover of the storage shelf does not transmit a remote control signal, the VTR 6 cannot be remotely controlled by a VTR remote control. . So, TV7 and VTR
6 by a cable or the like, the first remote control light receiving unit 3 and the microcomputer 1 are connected to each other.
The VTR 6 can be operated by a V remote controller. That is, when the VTR 6 is operated with the TV remote control,
The first remote control light receiving unit 3 receives a remote control signal, and the remote control signal is input to the microcomputer 1.

[0007]

However, in the above configuration, when the second remote control light receiving unit 2 can be used, the remote control signal received by the second remote control light receiving unit 2 and the first remote control light receiving unit 3 And the remote control signal from the microcomputer 1 are mixed by the microcomputer 1, and the microcomputer 1 cannot normally receive the signal from the remote controller.

[0008] The present invention solves the above-mentioned problems.
It is an object of the present invention to provide a magnetic recording / reproducing apparatus that can normally perform a remote control signal receiving process even when a remote control light receiving unit on the TR side can be used.

[0009]

According to the present invention, there is provided a magnetic recording / reproducing apparatus connected to an external device having a first remote control light receiving section capable of receiving a first remote control signal. And a second remote control signal capable of receiving the second remote control signal.
And a microcomputer to which a remote control signal received by the second remote control light receiving unit and the first remote control light receiving unit is input. The microcomputer receives the first remote control signal received by the first remote control light receiving unit. It is provided with a switch for switching ON / OFF of input to the microcomputer.

[0010] Thereby, even when the remote control light receiving section of the magnetic recording / reproducing apparatus can be used, the remote control signal receiving process can be normally performed.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The first and second aspects of the present invention are directed to a magnetic recording / reproducing apparatus connected to an external device having a first remote control light receiving section capable of receiving a first remote control signal. A second remote control light receiving unit capable of receiving a second remote control signal; and a microcomputer to which a remote control signal received by the second remote control light receiving unit and the first remote control light receiving unit is input. A switch for turning on / off the input of the first remote control signal received by the first remote control light receiving unit to the microcomputer is provided. With such a configuration, the switch is turned on, and the remote control signal from the television and the magnetic recording When the remote control signal received by the remote control light-receiving unit of the playback device is added to the microcomputer and input to the microcomputer, the remote control signal input by the microcomputer is input. Check the format of the remote control signal, and if it is not the proper format, determine that a collision has occurred and the microcomputer turns off the switch, and input only the remote control signal received by the remote control light receiving unit of the magnetic recording and reproducing device to the microcomputer. Thus, the magnetic recording / reproducing apparatus can operate normally with the remote controller.

An embodiment of the present invention will be described below with reference to the drawings. (Embodiment 1) FIG. 1 is a block diagram of a magnetic recording / reproducing apparatus according to the present invention. In FIG. 1, reference numeral 6 denotes a VTR which is a magnetic recording / reproducing apparatus, 7 denotes a TV which is an external device, 1 denotes a microcomputer, The remote controller signal input to the microcomputer is decoded, and V corresponding to the remote controller signal is decoded.
Various processing operations of TR6 are performed. Reference numeral 2 denotes a second remote control light receiving unit which is a remote control light receiving unit of the VTR 6, and a remote control signal converted into an electric signal is input to the microcomputer 1. Reference numeral 3 denotes a first remote control light receiving unit which is a remote control light receiving unit of the TV 7. The remote control signal converted into an electric signal here passes through the switch 4 to the microcomputer 1.
Is input to Reference numeral 4 denotes a switch for switching the input of a remote control signal from the first remote control light-receiving unit 3 to the microcomputer 1, which is normally connected and cut off when a control signal is output from the microcomputer 1. Reference numeral 5 denotes a control signal for switching on / off of the switch 4, which is output from the microcomputer 1.

One of the remote control signals is input to the microcomputer 1.

The microcomputer 1 constantly checks the input remote control signal, and receives a normal format, that is, a remote control signal from one of the first and second remote control light-receiving units 2 and 3 and inputs the remote control signal to the microcomputer 1. If so, an operation suitable for the operation, for example, various operation control of the VTR 6 such as recording and reproduction is performed. However, if the format is not a proper format, that is, both the second remote control light receiving unit 2 and the first remote control light receiving unit 3 receive the remote control signal at the same time, and the remote control signal is input to the microcomputer 1 in a mixed state. When the switch 4 is turned off, the control signal 5 is output so that the switch 4 is turned off.
