Definitions

  • the invention is based on a recorder according to the preamble of claim 1.
  • a recorder is known from DE-OS 35 04 311.
  • a test run can be used to determine the respective tape stand and the remaining amount of tape from the speeds of the winding plates.
  • a short test run of approx. 2 s is carried out and the remaining amount of tape remaining is then displayed in hours and minutes.
  • the counter is automatically reset to zero after the cassette has been inserted.
  • the invention is based on the object of developing such a recorder in such a way that, regardless of the respective tape stand, the operator is provided with optimal and fast absolute information about the tape stand and a rapid and convenient approach to desired tape positions is made possible.
  • the invention therefore ensures that the absolute tape stand is displayed in the form of a number immediately after the cassette has been inserted. In the absolute display, this is exactly the tape stand that would be displayed if the tape had run from the beginning with the counter in the zero position up to the mentioned tape stand. A return to the beginning of the band in order to count again from there with the counter is not necessary.
  • the tape stand displayed after inserting the cassette is automatically related to the beginning of the tape. It is advantageous that all previous operating means and other features in terms of operation can be retained unchanged.
  • the invention is particularly advantageously applicable to a video recorder.
  • the invention can also be used with other recorders such as an audio recorder, e.g. a DAT recorder or an analog audio cassette recorder. '
  • the counter can always be reset to zero manually, regardless of the current tape level.
  • the respective tape stand can also be designated as zero in the counter display as required.
  • the data of a manually entered cassette type are used to determine the tape stand. This is particularly advantageous in the case of cassettes of the type E195 and E300, because they cannot yet be automatically correctly recognized with such means.
  • FIG. 1 shows a video recorder with a cassette and not yet inserted
  • FIG. 2 shows the video recorder with an inserted cassette and the absolute tape stand display.
  • the counter 4 is in the zero position or in any other position from a previous play.
  • the cassette 5 is pushed into the cassette compartment 2.
  • the recorder 1 automatically starts a short test run of approximately 2 s.
  • the current tape stand is determined by measuring the number of revolutions of the belt disks, for example in accordance with DE-OS 35 04 311.
  • This determined absolute belt stand is immediately displayed in the form of a number with the counter 4 by d ⁇ e ⁇ number 2640. This is the number that would also be displayed if the tape had run from its beginning with zero counter start to the tape stand assumed in Fig. 2 in slow or fast running.
  • the belt travels a short distance of approximately 5 to 10 cm at increased speed. After the end of the test run and the determination of the belt stand, the belt is transported back this distance so that it has the original position regardless of the test run.
  • the counter 4 can be set to zero regardless of the respective band level. Then the current band stand according to FIG. 2, which would be measured 2640 per se from the beginning of the band, is designated 0000 at the request of the operator. The current bandstand 2640 is then deleted. In order to “determine” this current tape stand 2640 again and display it with the counter 4, only the cassette 5 is required to be removed from the cassette compartment 2 and inserted again. Then the current tape level 2640 is automatically determined again in the manner described and is displayed immediately afterwards with the counter 4.

Abstract

On cherche à obtenir que l'utilisateur, indépendamment de la position respective de la bande, reçoive une information la plus rapide et la plus pratique possible sur la position de la bande et qu'un redémarrage rapide soit possible à partir de la position de bande souhaitée. Après introduction de la cassette (5), la position respective de la bande est détectée automatiquement et le compteur (4) se règle sur la valeur absolue de cette position. Application notamment à des magnétoscopes VHS.
