Abstract

PURPOSE:To execute easily reproduction at a high speed, and also to obtain a correct output by obtaining queue and review states of a speed of two stages by the difference between operating methods of a reproducing command and a rapid traverse and rewinding command. CONSTITUTION:A mechanism operating state storage means 2 is provided in order to store in which state the present operating state of a mechanism is among, for instance, a reproducing running state, a sound recording running state, a rapid traverse operating state, a rewinding state, a queue state, a review state, a stop state, etd. A mechanism operating command discriminating means 3 is provided in order to receive a command from a mechanism comman means 1 and to discriminate its contents. A mechanism control means 4 gives a signal required for an operation of a mechanism 5 to the mechanism in accordance with information of the mechanism operating command discriminating means 3. In this way, when a reproducing command and a rapid traverse operating command, or the reproducing command and a rewinding command have been given simultaneously, monitoring can be executed in a state that a relative speed of a head and a tape is lower than a usual que or review operation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a recording and reproducing apparatus that performs cue or review operations.

Conventional configuration and its problems In tape recorders, the monitor sound during cue (or review) operations is relatively easy to hear at the beginning (or end) of tape winding, but as it approaches the end (or beginning) of winding. It becomes harder to hear over time. This is because the tape reel is rotated by constant rotation of the reel stand of the mechanism, and the tape movement speed increases due to the difference in the amount of tape winding. Conventionally, the number of rotations of the reel during cue (or review) was constant, so especially at the end of winding (or at the end of winding), the winding and winding radii become large and the tape movement speed increases.
The drawback was that the monitor sound was difficult to hear. Furthermore, when trying to find a specific recorded portion on a tape, the tape moves at a high speed, so conventional cue (review) operations have difficulty, such as excessive forwarding.

OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned drawbacks, and aims to provide a recording/reproducing apparatus that can realize a high-speed or low-speed cue (review) state depending on the difference in operation commands to the same operation member.

Structure of the Invention The present invention provides a mechanism operation state storage means for storing the current operation state of the mechanism, a mechanism operation command determination means for determining the content of the mechanism operation command from the mechanism command means, and information from the mechanism operation command determination means. and a mechanism control means for giving playback, fast-forward, two-rewind, normal cue-review, slow-speed cue-review and other commands to the mechanism, and gives a fast-forward (or rewind) command in the playback state. and a normal cue (or review τ) operation, and if a play command and a fast forward command (or a play command and a rewind command) are given at the same time, the tape movement speed will be lower than that of a normal cue (or review). This enables a low-speed cue (review) operation to be performed, and reduces the frequency difference in high-speed reproduction signals caused by the difference in the amount of tape wound.

DESCRIPTION OF THE EMBODIMENT FIG. 1 is a functional block diagram showing an embodiment of the present invention. Reference numeral 1 denotes a mechanism command means, which is generally composed of a switch, and is used by the tape recorder user to give commands to the mechanism of the tape recorder. Reference numeral 1a denotes a regeneration command means for giving a regeneration command 4 to the mechanism. 1b is a fast forward (or rewind) command means for giving a fast forward (or rewind) command to the mechanism.

Reference numeral 2 denotes a mechanism operating state storage means in which the current operating state of the mechanism is stored, for example, in a playback running state, a recording running state,
It stores which state it is in, such as fast forward state 2 rewind state, queue state, review state, stop state, etc. Reference numeral 3 denotes a mechanism operation command identifying means, which receives a command from the mechanism command means 1 and identifies its content. Reference numeral 4 denotes a mechanism control means which, in accordance with the information from the mechanism operation command identification means 3, provides signals necessary for the operation of the mechanism 5 to the mechanism.

FIG. 2 is a circuit diagram showing a specific configuration of this embodiment.

1a, 1b', and s are the same as the corresponding symbols in FIG. b is a microcomputer which includes means 2, 3.4 in FIG.

FIG. 3 is a main part flowchart for explaining the operation of the microcomputer 6 of this embodiment.

The operation of this embodiment with the above configuration will be described in detail below. First, when the user does not give any command to the mechanism, no change is given to the microcomputer 6, and the program repeats path 7b upon determining that the step is complete.

Next, a route when a regeneration command is issued, for example, will be explained. According to the judgment of the microcomputer 6, the step is completed and route 71 is reached! L is taken and steps are reached, where a command from the mechanism command means is identified. In this step, it is determined whether the command from the command means is a simultaneous playback and fast-forward command, or a simultaneous playback and rewind command.

In the case of only a regeneration command, route 8b is taken here, and in step 9, mechanism control (regeneration operation here) according to the operation command is performed, and step 1.
At this point, the mechanism operating state is stored. In the same way, fast forward, rewind, and record.

Outages and normal queue reviews, etc. also follow this path.

On the other hand, if you press play and fast forward or play and rewind at the same time, step 7, route 7a, step 8, route 8
a and gives the mechanism a slow queue review command in step 1o, leading to step 11. The above-mentioned step 9 also includes a cue review operation, but the cue review operation in step 10 is a cue review operation in which the rotation speed of the reel stand is lower and the tape movement speed is lower than in the cue review operation in step 9. - A review operation is performed.

With the above operation, when a playback command and a fast-forward command, or a playback command and a rewind command are given at the same time, it is possible to monitor at a lower relative speed between the head and the tape than in a normal cue or review operation. Regarding the correspondence between the flowchart in FIG. 3 and the functional block diagram in FIG.
1, the operation of the mechanism operation command identifying means 3 corresponds to step T and step 8, and the operation of the mechanism control means 4 corresponds to step 9 and step 10.

Effects of the Invention The present invention enables high-speed playback by obtaining a two-speed cue/review state by using the difference in the operation method of the playback command, fast forwarding, and rewinding commands without providing a specific input cue inch. This makes it possible to realize an excellent recording and reproducing apparatus that can obtain appropriate output.
