Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a chronological table of history, and relates to a tape measure chronological table in which a user can study any period or period in a list and is convenient to carry.

[0002]

[Prior art]

 Conventional chronology is printed on books or cards. Therefore, while the history of the limited period printed on one page or a single sheet of the book could be learned in a comprehensive manner, for the longer period, the page is newly turned. Or I had to replace it with a new card. In particular, history is almost meaningless in short-term lessons, and as one traces the flow of a river, it traces the flow of the times and explores the historical facts that occurred at each time and its background or the social environment before and after it. One of the learning objectives is to guide the present and future in the right direction, and to do so, replace any period of continuous flow with a new card without turning the page. However, it is most important to be able to study visually through a list, but conventional books and chronological tables have the drawback that such learning is completely impossible.

When learning history while observing historical sites and the like, carrying a chronological table is an essential item, but conventional books and card-type chronological tables are stored in pockets or the like. However, it has the drawback of being too bulky and inconvenient to carry, and historians strongly urged the immediate development of a chronological table that is easy to carry.

[0004]

[Problems to be solved by the device]

 The present invention was made in order to solve the drawbacks described in the prior art, and an object thereof is to provide a tape-type chronological table that allows a user to learn a list of desired periods or eras and is easy to carry. It was done.

[0005]

[Means for Solving the Problems]

 On the mandrel that automatically rewinds and stops at any position, or the mandrel that can be manually rewound, wrap the paper with the chronology printed or the plastic sheet on the beginning of the pedestal. At the end of the paper or plastic sheet on which the chronology from the entrance / exit groove is printed, attach a chronograph stopper having a width larger than the width of the entrance / exit groove. In order to make it easier to carry around, a locking pin for locking the clothes pocket is attached to the top of the case.

[0006]

[Action]

 You can pull out the chronology of any period you want to study, and after learning, rewind it on the mandrel and store it in the case. Prevents the chronological stop bracket from being rewound into the case. The cylindrical case with the locking pin for locking has a shape similar to a fountain pen, which makes it extremely easy to carry.

[0007]

【Example】

 A drawing showing an example of the implementation of the present invention will be described. A mandrel 1 that automatically rewinds and stops at an arbitrary position or a mandrel 1 ′ that can be manually rewound is printed with a paper or plastic sheet on which a timeline is printed. -The start end of the sheet 2 is fixedly wound, and the paper or the plastic sheet 2 on which the chronology is printed out from the inlet / outlet groove 4 of the cylindrical case 3 or 3'made of plastic is attached to the end of the inlet / outlet groove 4 Attach the chronological stop fitting 5 having a width larger than the width. Reference numeral 7 denotes a spring mechanism for automatically rewinding the mandrel 1, and any known spring mechanism used for a tape measure or the like can be applied. Reference numeral 8 is a knob having a knurled groove whose inner surface is in close contact with the mandrel 1 and whose movement in the circumferential direction is restricted, but is free to move in the vertical direction.

Reference numeral 9 denotes a knurled groove that fits into the knurled groove of the knob 8 provided on the case 3, and the knurled groove of the knob 8 fits into the knurled groove of the case 3. Then, the mandrel 1 is restrained, and when the knurled groove of the knob 8 is released, the mandrel 1 is released from the restraint. When the knob 8 is normally removed from the knurled groove of the case 3, the chronologically printed paper or plastic sheet 2 can be pulled out from the entry / exit groove 4 and stopped at any position. When the knob 8 is pushed, the knob 1 is fitted into the knurled groove 9 of the case 3 to restrain the mandrel 1. When the knob 8 is disengaged from the knurled groove 9 of the case 3, the spring mechanism 7 rewinds and automatically rewinds the paper or plastic sheet 2 on which the chronology is printed. Reference numeral 10 is a knob fixed to the top of the mandrel 1 '. By manually rotating this knob, the paper or plastic sheet 2 on which the chronology is printed is rewound into the case 3'. be able to.

Reference numeral 6 is a retaining pin (3 'is omitted because it is a similar drawing) attached to the tops of the cylindrical cases 3 and 3'. Used when carrying cases 3 and 3'locked in clothes pockets or the like. The chronology may be printed on only one side or both sides of the paper or plastic sheet 2. It is preferable to display the chronological table, for example, in the upper column of the Christian era, the middle column of the zodiac, the lower column of Japanese history, and the cases related to that era in the lower column because it is easier to learn.

[0010]

【effect】

 Since the present invention is configured as described above, it has the following effects.

Since historical facts over an arbitrary period or period can be visually learned in a list, the learning effect is significantly improved.

Since it can be locked in a pocket of clothes, it is extremely easy to carry. This device has the above-mentioned effects, and its industrial utility value is high.
