Abstract

PURPOSE:To attain multifunctional operation of a controller for tape recorder with less input ports by using such constitution where the input of a forward reset switch is applied in a non-reproduction mode of a reproduction switch together with the input of a reverse switch applied in a reproduction mode respectively for execution of the same control. CONSTITUTION:An address designating means 2 designates an address in a memory means 3 starting at a step 1 and decides in a step 2 whether the input is equal to a reverse switch 1a or a forward reset switch 1b. When the switch 1a is decided, a motor 7 is turned on since a reproduction switch 1c is turned on. Then the commands are outputted to a plunger control output circuit 4 and a motor control output circuit 6 for drive of the motor 7 and a plunger 5 respectively. Then the control is carried out to invert the mechanism. When it is decided that the input is equal to the switch 1b, the switch 1c is turned off and therefore no operation is carried out as long as the tape driving direction is forward in a tape mechanism. While the inversion control and the forward reset control are carried out in case the tape driving direction is reverse. Thus it is possible to attain multifunction control of a tape recorder with a small number of input ports and small memory capacity.

Description

DETAILED DESCRIPTION OF THE INVENTION 3. Detailed Description of the Invention Field of Industrial Application The present invention relates to a control device by Cheaple and Korg that uses electrical means to control a drive circuit for a tape mechanism.

2. Description of the Related Art In general, a control device for a tape mechanism of a tape recorder, as shown in FIG. The forward rotation reset switch 1b, which switches the running direction to the forward rotation side, is an independent input of the addressing means 2, and the pull-up resistor 11a
, 1 l b.

Reverse switch 1a, forward reset switch 1b, regeneration switch 10.110.11d.・・・・・・、
an address specifying means 2 for specifying an address for starting a control operation based on input information from a switch group 10 of a tape running direction switch 1n; a storage means 3 for storing control information for a planar jar 6° motor 7; and a storage means 30 for storing control information. The tape mechanism is controlled by a plunger control output circuit 4 which has a control means 12, which drives a plunger 5 for switching the tape running direction via the control means 12, and a motor control output circuit 6 which drives a motor 7 for tape running. The configuration was as follows. Further, as shown in FIG. 4, the control procedure includes independent starts corresponding to the respective inputs of the reverse switch 1a and the forward reset switch 1b.

Problems to be Solved by the Invention However, in the above-mentioned control method, separate control steps are required for the number of input ports of the addressing means 2, the reverse operation and the forward rotation reset operation, and therefore the capacity of the storage means 3, etc. This increases the number of input ports and may lead to a shortage of storage capacity, resulting in a problem that a control device must be configured with a larger number of input ports and storage capacity than necessary.

The present invention solves the above problems and provides a control device for a tape recorder that has a small capacity and is multifunctional with a small number of input ports.

Means for Solving the Problems The control device of the present invention includes a regeneration switch for inputting the regeneration state and a reverse switch for switching between forward and reverse rotation.

A forward/reverse mode switch that inputs the forward/reverse state.

a switch means including a forward reset switch linked to opening and closing of the cassette lid; an address designation means for specifying an address to start control based on each switch information of the switch means; and drive of the tape mechanism according to the designated start address. It has a storage means corresponding to controlling the circuit, and a control means for outputting a control signal for controlling the drive circuit, and the switch means connects a reverse switch and a forward reset switch as the same input to the addressing means. However, when the regeneration switch is in a non-regeneration state, an input from a forward reset switch is applied, and when the regeneration switch is in a regeneration state, an input from a reverse switch is applied.

According to the above-described structure, the present invention distinguishes the inputs of the forward reset switch and reverse switch connected to the same input port by opening and closing the playback switch of the tape recorder, and the tape runs in the forward direction by opening the cassette cover. The two functions of a forward reset function for setting the system and a forward/reverse switching function for manually reversing the tape running system during playback can be realized with a small storage capacity and a small number of input ports.

Embodiment Hereinafter, a control device according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an embodiment of the invention. In FIG. 1, a switch group 1 includes a reverse switch 1a, a forward reset switch 1b, a regeneration switch IC, . . . , and a forward/reverse mode switch 1n. Reverse switch 1a
is connected in series with the regeneration switch 1c, so the input condition of the reverse switch 1a is an AND configuration with the regeneration switch 1c being ON. Forward rotation reset switch 1b
The contact part 8, which also serves as a spring to open the cassette lid,
transistor switch 9
Since the base bias ",H" is applied through the pull-up resistor 1o of the regeneration switch 1G when the contact portion 8 is open, the input condition of the genuine reset switch 1b is ANDed with that when the regeneration switch 1C is OFF. In addition, addressing means 2. Storage means 3. Control means 12. Control output circuit for plunger 6 4. A control output circuit 6 for a motor 7 is provided.

FIG. 2 is a flowchart showing that with the above-described configuration, the addressing means 2 uses the same control method regardless of whether input is applied from the reverse switch 1a or the forward reset switch 1b.

Regardless of the above input, when the address designation means 2 specifies an address in the storage means 3 starting from step 1, the above input is input to the reverse switch 1 in step 2.
Distinguish between switch a and normal rotation 7) switch 1b. In the case of the reverse switch 1a, since the regeneration switch 1C is ON, the motor 7 is turned ON in step 3, and then in step 4, a command to drive the motor 7 and plunger 6 is output to each control output circuit 4.6, and the mechanism is activated. Perform inversion control.

On the other hand, if the above input is the forward rotation reset switch 1b in step 2, the playback switch 1C is OFF, so proceed to step 5, and in step 6, if the state of the tape running direction of the tape mechanism is on the forward rotation side, nothing is done. If it is not operated, and it is on the reverse side, normal rotation reset control is performed in step 3.4, which is the same as the above-mentioned reversal control.

As described above, by providing the reverse switch and the normal rotation reset switch with an AND operation with the opening/closing of the regeneration switch, the same input port and the same control command can be used.

Effects of the Invention As described above, in the present invention, the regeneration switch, reverse switch, and forward reset switch are connected to the same input of the addressing means in an AND configuration, so the same input port and the same control command can be used. This makes it possible to realize a multi-function control device for a tape recorder with a smaller number of input ports and a smaller storage capacity.
